Application filed February 5, 1915. Serial No. 6,249.

To all whom it may concern:

Be it known that I, THOMAS STEWART, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Locomo-. tive-Tenders, of which the following is a specification.

My invention relates to new and useful improvements in locomotive tenders, and

has for its object to provide an exceedingly simple and effective device of this character which will prevent the shifting of the entire body of water carried in the tank of the tender, thus reducing to a minimum. the possibility of accidents due to this cause.

A further object of the invention is to construct the water tank of a locomotive tender of a number of horizontal superimposed compartments whereby the water in the uppermost compartment only will be able to move about, and the amount of water in each compartment will be practically insuliicient to cause any accident by such shifting of the water.

A still further object of the invention is to arrange a number of spaced parallel horizontal partitions within the tank of a locomotive tender in order to form a plurality of compartments, each of which is in communlcation w1th the ad acent compartments,

through the openings in said partitions, certain of saidopenings having automatic or float valves adjacent thereto for closing the same.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

I In order that those skilled in the art to which-this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numeral to the accompanying drawing forming a part of this specification, in which- I Figure 1, is a vertical sectional longitudinal view of a tender embodying my invention, showing the same coupled to a locomotive; and Fig. 2, is a section at the line 22 of Fig. 1, looking in the direction of the arrow.

' In carrying out my invention as here embodied 2 represents a locomotive having a tender 3 coupled thereto.

The tender 3 is divided into a coal bin the scoop 8 adapted to receive water from the trough 9, from which point the water is conveyed to the top of the tank by means of the intake pipe 10.

The water tank 5 is sub-divided by means of suitable parallel partitions 11 into a number of horizontal super-imposed water compartments 12', each of which is in communication with the adjacent compartments through the inlet openings 13, and the vent openings 1% formed, in the partitions,

The inlet openings 13 to each of the com- 'pa-rtments are closed by suitable valves 15 which will float upward as the compartments are filled, and automatically close the openings 13, the valves here shown being as the ordinary hinged flapper valve of leather or other suitable material their downward or opening movement being limited by suitable brackets or steps 16. Y

The water is drawn off from the bottom of the water tank, and delivered to the loco motiveboiler by means of the ordinary out let pipe 17.

in practice the water tank of the locomotive tender is tilled at the top in the ordi nary manner, the water first entering the uppermost compartment lie through the different inlet openings 13 through the different compartments into the lowermost one, and as said lowermost compartment is full, the valve controlling the inlet opening thereto will float upward close the inlet opening, and in like manner each of the compartments will be tilled until the entire tank is full. The water drawn oii from the water tank in the ordinary manner and fed to the locomotive boiler, and liS the outlet pipe leads from the lowermost water compartment, the water from said compartment will be kept at its ordinary level by the supply from the succeeding superimposed compartments. As the tender travels over the track the same receives a swaying motion from a number of different well known causes, which 1n the case of the ordinary tender causes the water to be splashed about and shiftedconsiderably, which has a tendency to overturn the tender, thereby causing accidents with great loss of life and property, bu by the use of Cir my improvement the water in the filled com-- partments ,Will be unable to splash about and the amount of water in any of the unfilled compartments being so small relatively that the shifting thereof will not cause the tender to capsize. The inlet Openings 13 being closed by the valves 15 when the compartments are filled, will prevent the water from one of the filled compartments from entering the unfilled compartment during the swaying of the tender, and should any of the valves for any reason stick and not tion, what I claim as new and useful, is-

1. A locomotive tender provided with a water tank, a-plurality of partitions therein for sub-dividing the same into a number of superimposed compartments, said partitions having openings therein, certain of which,

are valve controlled.

2. A locomotive tender provided with a water tank, a plurality of partitions therein for sub-dividing the same into a number of superimposed compartments, said partitions having openings therein, and valves for controlling certain of said openings.

3. A locomotive tender provided with a water tank, a plurality of partitions therein for sub-dividing the same into a number of superimposed compartments, said partitions having openings therein, valves for controlling certain of said openings, and means for limiting the opening movement of said valves.

4. A locomotive tender provided with a water tank, a plurality of spaced horizontal partitions extending the entire length and width of the tank for dividing the interior thereof into a plurality of relatively low compartments extending the entire length of the water tank, each of said partitions having two different size holes therein, the

smaller hole designed principally for the outlet of air, a valve hinged to the underside of each of the partitions for controlling the larger openings, and means for limiting the opening movement of said valves.

In testimony whereof, I- have hereunto afiixed my signature in the presence of two subscribing witnesses.
